We report on five patients with a clinical presentation of corticobasal degeneration (CBD), including gradually progressive, asymmetric, L-DOPA-resistant parkinsonism associated variously with apraxia, focal action myoclonus, focal dystonia, cortical sensory loss and alien limb phenomenon. Some patients also presented an atypical CBD clinical history or signs - notably sudden onset. The disease was however not suggestive of another diagnosis. Magnetic resonance imaging of the brain revealed extensive vascular lesions. Only five similar cases have been published to our knowledge. Although we cannot exclude underlying CBD pathology, our cases illustrate the fact that multi-infarct pathology can masquerade as CBD or alter the clinical phenotype of the disease.
